Michael Savage is fun to listen too but not very smart. If you have education and share his position, you will suffer some times. It's not as revolting when an ideological enemy says obvious crap. When someone on your side does it, it hurts.
Hannity is much better - as long as you realise that he stands on religious position. Allowing for that, he is quite consistent in most cases. Still he too often misses obvious points. I often think "I could have rebuttled that liberal caller much better"...
Steve Molsberg seems to be the smartest one of conservative guys so far. He hosts a show with Richard Bey (liberal) in NY area, right after Hannity.
